MACHINE FOR MAKING HEAD-BANDS FOR BOOKS.

Specification of Letters Patent.

Patented Aug. 2, 1910.

Application filed. September 20, 1904. Serial No. 225,225.

To all whom it may concern:

Be it known that I, ADOLPH G. Horn SGHER, of Norwood, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improve ments in Machines for Making Head-Bands for Books, of which the following is a specitication.

The subject of the present invention is a machine for making headbands which consist of pieces or lengths cut from a strip of cloth folded double lengthwise and having the thickness of the folded edge increased by apiece of string placed in. the fold eX- tending longitudinally of the strip, for use in binding books. The headbands are saturated with glue or paste and are applied to books during the process of binding, being placed on the backs of the books insideof the outer coverings after the signatures are stitched together with their enlarged edges projecting over the upper and lower rear edges of the book to cover the folded edges of the signatures and hide the irregularity caused by the projection of these edges.

Hitherto headbands have been made by hand by taking strips of cloth about an inch wide and as long as can conveniently be manipulated, usually about two feet, flding them over strings stretched between suitable supports and pasting the flaps together. This method is slow and expensive, as skilled operatives must be employed and the amount which any operative can produce by hand is limited. I have therefore devised a machine by which headbands can be made more rapidly and accurately than by hand and of which the output is practically unlimited, while only slight attention is necessary to maintain it in operation.

The machine illustrated in the accompanying drawings and hereinafter described and claimed constitutes the preferred embodiment of my invention. 1

In the drawings Figure 1 represents a side elevation, Fig. 2 represents an end elevation, Fig. 8 represents a plan view, and F 4t represents a longitudinal vertical sectional view of a machine embodying my in vention. Fig. 5 represents a perspective detail view of a'folder and stringguide used in connection with this machine.

The same reference characters indicate the same parts in all the figures.

In this machine a breadth of cloth 1 is taken from a roll 101 supported by brackets 102 on the frame of the machine, and is caused to pass by rotary cutters 2 3 which are mounted on parallel shafts 1 and 5 carried by the machine-frame and are operated in connection with each other to cut the breadth into a plurality of strips 7. These strips are preferably about an inch in width, although they may be of any desired width, and any desired number may be formed from a breadth of cloth. After passing the cutters the strips are drawn over guide-rolls 103 and through folders 6 which fold the strips double and have provisions for guiding strings 14 so that they will lie in the folds of the strips. From the folders the strips pass overthe guide-rolls 1045 through the feed-rolls 10 11 to the cutters 12 13 which sever pieces from the ends of the strips of the proper length to make the completed headband. After being severed by the cutters 12 and 13, the headbands fall upon the conveyer 18 which is supported on a table or bracket 19 in close proximity to the cutters, and. is caused to move transversely. of the machine to carry away the headbands. In order to distinguish the rotary cutters 2 3 which slit the cloth longitudinally into strips, from the reciprocating cutters 12 18, which chop off the completed headbands, the former cutters may be conveniently considered and called slitters. The conveyer consists of a belt or tape which is supported on a stud 51 on the frame of the machine in the form of a roll and is led over a guide 65 and the table 19 past the cutters, and is then rolled up over the stud 53 by means to be hereinafter described to form a roll 52 between the'convolutions of which the completed headbands are held.

21 is a receptacle or tank adapted to contain a quantity of paste, glue or other adhesive material, and the folders 6 are mounted on the lower part of the bracket 8 in such manner that they normally extend beneath the level of the paste and are submerged therein. The guide-rolls 103 10 1 are located so as to guide the fabric strips into the paste receptacle and through the paste. The bracket 8 is pivotally mounted at 9 to the frame of the machine so that it can be rotated to bring the folders out of the paste whenit is necessary to thread .new pieces of string and strips of fabric through the folders.

Any desired folder having provisions for doubling over the edge of a strip of cloth and for guiding a string so that it will lie snugly in the fold may be used, one such folder being shown in Fig. 5. This folder contains a fiat guide-plate a and a curved plate 5 which partially surrounds the guideplate a and turns one edge of the strip over the guide-plate in the manner shown by dotted lines in Fig. 5. The guide-plate a is provided with holes 0 which receive and guide the string 14 to cause it to lie snugly within the folded edge of the strip. The string is contained in a receptacle 16 from which receptacle a string is led to each one of the folders. While passing through the paste the strips become thoroughly saturated therewith so that after they have passed the folders and lower guide-roll 104 and emerged from the paste, the folded-over flaps are firmly stuck together and constitute with the strings strips which are of half the original width of the strip 7, having one edge thickened and which may, for convenience, be called headband strips. The feeding rolls consist of the lower cylindrical roll 10 and the upper roll 11 which is formed with grooves 64 so spaced as to accommodate the enlarged edges of the headband strips. The lower roll is mounted in fixed bearings while the upper roll is mounted in bearing-bloeks 22 which are adjustable in vertical guides 23 by means of screws 24 to vary the pressure which they exert on the headband strips. The rolls are positively geared together by means of pinions 25 carried by their axes and meshing together, and are driven intermittently by mechanism consisting of a ratchet-wheel 26 carried on the axis of one of the rolls and operated by a pawl 28 carried by an arm 27 which is loosely journaled on the same axis. A spring 29 retains the pawl 28 in engagement with the ratchet-wheel. The arm 27 is oscillated to move the pawl 28 backward and forward and so advance the feed-roll step-by-step through a pitman 30 which is pivoted to the end of the arm and the other end of which is mounted on a crank-pin 31 carried by a crank-disk 32 on the end of the main drive-shaft 35. The step-by-step rotation of the feed-rolls draws the strips through the folders and advances the free ends of the strips to the cutters.

As it is desirable to have the machine produce headbands of different lengths, provision is made for varying the amount of the feed, and to'this end the crank-pin 31 is formed on a block 105 mounted in a diametrical slot in the crank-disk, and a screw 34 which takes into the block 105 is also mounted in this slot, as shown in Fig. 1. By rotating this screw the eccentricity of the crank-pin may be varied and thus the distance through which the feed-rolls and the headband strips are advanced at each rotation of the driving-shaft may be either increased or diminished, thereby increasing or diminishing the lengths severed by the cutters to form headbands.

The severing cutters comprise the fixed knife 12 and the movable knife 13 which is carried by a vertically-reciprocating cross bar 17 and coacts with the fixed knife to shear off pieces from the ends of the headband strips. The ends of the cross-bar 17 are connected to vertical plunger-rods 39 which are caused to move up and down bv the rotation of the drive-shaft 35 through a cam 36 carried by said shaft which aetuatcs an arm 37 attached to a rock-shaft 3370. Upon the ends of the rock-shaft are mounted arms 38 which are connected at 40 to the plungers 39. As will be readily seen, the rotation of the shaft 35 causes oscillation of the rock-shaft 370 and thereby raising and lowering of the movable knife 13.

The means for operating the conveyerbelt will now be described.

The drive-shaft 35 carries on one end a pulley 46 which by means of a belt 45 drives a pulley 44 on a counter-shaft 43. On this counter-shaft is a friction-drum 41 which is mounted beneath the stud 53 about which the conveyer-belt is wound. The stud 53 is carried by an arm 54 pivoted at 56 to a bracket 57 on the machine-frame and pressed downwardly by means of a weight 55 carried by the arm. The free end of the conveyer-belt is wrapped about the stud 53 and is caused to rest upon the drum 41. The weight 55 causes the belt to bear against the drum 41 with suflicient friction so that rotation of the drum causes the conveyer to be carried past the knives and to be wound up on the stud 53.

In order to cause the conveyer to remain stationary while headbands are being ered from the ends of the strip, a means is provided for moving the conveyer out of contact with the drum 41 while the upper knife is performing its cutting stroke. This means comprises a lever 58 pivoted at 62 to a bracket 61 and having an operative connection at 59 with one of the plunger-bars 39 and having at its other end a projection 63 which is adapted to engage one of a series of teeth formed upon a bar 60 which is carried by the arm 54 and hangs vertically downward therefrom. As the upper knife is lowered to cut, the left-hand end of the lever 58, as seen in Fig. 2, is lowered, while the right-hand end is raised, thereby raising the bar 60 and elevating the arm 54 to carry the roll 52 out of engagement with the drum 41, thus rendering the driving connection inoperative and causing the conveyer to remain stationary. Flanges 42 are formed on opposite ends of the drum 41-1 and extend on both. sides of the roll 52 to guide the conveyer-tape as it is wound up on the roll.

By reason of the construction of the driving mechanism above described the speed of the conveyer-tape is always uniform regardless of the diameter of the roll 52 which constantly increases. The belt is formed preferably of felt or similar material and is kept wet in order that the paste-saturated headbands which are rolled up with it will-not stick to it. After all of the tape has been unwound from the roll 50 and wound up on the roll 52 the latter is removed from the stud 53 and taken to a work-table where headbands are being applied to books in process of binding, or if not needed for immediate use is put where it will remain wet until wanted.

In the form of the invention shown in the drawings the rotary cutters 2 and 3 are continuously driven by means of a gear 48 carried by the shaft 4 in mesh with a gear 47 on the counter-shaft 43, the two cuttershafts at and 5 being positively connected by pinions 49. However, I do not desire to restrict myself to this manner of operation as it is sometimes desirable to have the shafts i and 5 act as feed-rolls in order to diminish the strain put upon the headband strips when all of the feeding is performed by the rolls 10 and 11. In this case the spaces between the cutters on the cutter-shafts t and 5 are occupied by resilient rolls which grip the fabric strips, and the rolls instead of being driven continuously are suitably geared so as to operate synchronously with the rolls 10 and 11.
